Anhydrous. A crystalline powder originally derived from citrus fruit, now produced by
pure microbial fermentation of glucose derived from corn products. Widely used in foods, beverages
and cosmetics. Used to adjust pH in formulas including creams and lotions and other toiletries.
A primary ingredient combined with baking soda in fizzing formulas like bath bombs, bath seltzers
and fizzing bath salts. When citric acid and baking soda are combined and then mixed with water a chemical reaction occurs
that releases carbon dioxide, thus the "fizz". Used as a buffering agent. Mixed with water to make an
acid rinse for hair to lower pH after shampooing with soap. An alpha hydroxy acid used in personal care products
to adjust the acidity or promote skin peeling and re-growth in the case of anti-aging products.
When used as an AHA according to Health Canada: "Permitted at total concentrations equal to or less than 10%,
with a pH equal to or greater than 3.5. Preparations containing higher concentrations of AHAs may be permitted
for professional use if the manufacturer provides Health Canada with evidence of their safety, pH levels, and
the directions for use. The inner and outer labels of all leave-on skin products containing AHAs at concentrations
equal to or greater than 3% shall carry cautionary statements to the effect: 'Use only as directed', 'Avoid contact with the eyes',
'If irritation persists, discontinue use and consult a physician', 'It is recommended that prior to exposure to the sun,
users cover areas where AHAs have been applied with sunscreen', 'Contact of the product with the skin must be of limited
frequency and duration.' Preparations intended to be diluted in bath water may contain levels of citric acid exceeding 10%."
Used as a preservative in food products. Acts as a chelating or sequestering agent and preservative that helps to prevent
